I've tried all kinds of mouse alternatives over the years, and none has been entirely satisfactory. But I'm liking Apple's new Trackpad device better than the trackballs, pen-based devices, etc. For Logic, the best part is that it's large enough to "tap-and-hold drag" a fader like a physical long throw fader, this is MUCH more like operating a fader than using a mouse, because you'd ordinarily just glide a fader with a single finger in the real world. Bonus: Enabling the drag and secondary function options means that I can avoid the sore hand muscles I get holding down the click function on a mouse, trackpad or trackball, as this is the thing that usually bothers me most (this may be due to arthritic changes in my hand, but I've been having sore hand and fingers over the course of a long day in the studio for years). The mouse may or may not still be useful for detail work, but so far I haven't needed it since learning how to use the trackpad's features. Since I've enabled the options that let me avoid physically pressing and clicking with my fingers, my hands aren't sore at the end of a session. This is a useful tool worth trying, and I'm saying this as someone who doesn't like the trackpads on laptops due to their size. It's also cool not to have cables as it's bluetooth, and it's small enough to sit on top of a keyboard controller, etc. Good product. It works.
